N2 - In this paper, we have discussed the cosmological features of a fourth order model of gravity, having a free length parameter (constant or time dependent), and no cosmological constant or dark energy. By making a suitable choice for the present Hubble parameter and value of third derivative of the scale factor (the jerk), we have shown that the model can explain several cosmological features (like the late time cosmic acceleration) of the present universe to the same degree of accuracy as the standard concordance model. The equation of state and the redshift drift, also studied in this context, serve to discriminate our model from the standard model.
